(Cl. 168-4) The present invention relates to horseshoes In Fig. 1, 1 denotes holes for shoe nails passing which consist of rubber or similar yielding matethrough nail attaching members or inlays 2 of rial, in the interior of which there are embedded metal embedded in the rubber body 3 of the shoe, parts of metal or other stifi material, partly in in such a position that a curve through the nail 5 order to reinforce the shoe and partly to afford holes follows approximately the normal nail 60 attachments or attaching members for the ordihole curve of an ordinary iron horse shoe of the nary horseshoe nails. Such shoes are frequently size in question, whereby the nail holes by a simprovided with changeable resilient connections ple bending of the two shoe branches in relation extending between both rubber branches of the to one another may be easily Caused take a shoe and having for their purpose to cause said fit position to the hoof. According to Fig. 1 this 66 branches to remain in a relative position, wherein rubber forms also a rear transverse connection 4 the nail holes in the embedded metal parts are (ring sh h a inlays 2 a d h es 1 are in proper relation to the horse hoof.

whose bight is passed through holes in nail inlays on one shoe side and whose free ends pass through similar holes in the inlay 2 on the opposite shoe side and are twisted together outside the inlay as at 12, after having been adjusted in length. The transverse members may be in the form of ribbons or plates and be attached to 10 the inlays in several other manners. Two of them may be combined into a single stifi transverse member.

In Fig. 3 it is assumed that all nail inlays on either shoe side are united into an integral iron inlay 20. These two inlays are pivotally interconnected by a rivet 13 at the shoe front, whereby the two shoe branches may be easily adjusted relatively to one another in the transverse direction of the shoe. This adjustment being made 0 according to the size of the hoof, the position is fixed by the transverse members, for instance by 5, 5' or 11 as described above or by a solid bar 15 which is inserted from one shoe side and has beforehand a head 14 in that end, Whereas the 5 head 16 in the other end is made by riveting. Or the transverse member may be a flat iron bar 25 which is fastened to the nail inlays 20 by rivets 17, 18, its ends being placed in. recesses 19 and 21 in the rubber material 3. Such bars 25 may --be held in store in different lengths, and a bar is then chosen with a length suitable in any special case.

If the inlays are made as shown in Fig. 3, it will frequently be sufficient to use a single strong member 25, if the parts 20 are stiff enough. If they are more easily deformable, two transverse members may be desirable. And if the nail inlays are a plurality of separate'pieces as in Fig. 1, it might be suitable to use three members or 40 any desired member.

innermost of which is tubular in portions surrounded by the uttermost part so as to enable a fixed connection of the parts of said member in adjusted condition by clamping fiat the telescopically intermeshing portions at a suitable place in the fitted position of the branches so as to transfer an outwardly directed force on one inlay as an inwardly directed force on the connected opposite inlay.
